Polyethylene (polyethylene, PE for short) polyethylene is divided into linear polyethylene and branched polyethylene according to the structure of the polymer chain.
It is usually divided according to density into high density polyethylene (HDPE), medium density polyethylene (MDPE), low density polyethylene (LDPE) and linear low density polyethylene (LLDPE).
.
The main parameters of polyethylene are density and melt index. Density characterizes the tightness between the long main chains of the polymer and the regularity (or crystallinity) of the structure; melt index characterizes the relative molecular weight of the polymer.

Specification
High density polyethylene (HDPE), commonly known as low pressure polyethylene, is a copolymer of ethylene and a small amount of alpha-olefin, with a density of 0.941-0.96 and a melting point of 131-137°C. It has high temperature resistance, oil resistance, steam permeability and resistance to environmental stress cracking, excellent electrical insulation, impact resistance and cold resistance, and is mainly used for blow molding, injection molding, extrusion of pipes, films, profiles and rotomolding of large hollow products, etc.
Low density polyethylene (LDPE) is commonly known as high pressure polyethylene, the irregularity of the branched chain structure makes LDPE less crystalline, with a lower density of 0.910-0.925 and a lower melting point of 105-115°C. It has good flexibility, extensibility and transparency and is mainly used for the production of plastic bags, agricultural films, etc.
Linear low density polyethylene (LLDPE), is a copolymer of ethylene and alpha-olefin such as 1-butene (C4), 1-hexene (C6) and 1-octene (C8), copolymer monomer content of 8%-10%, its molecular chain does not exist long branched chain, has a narrower molecular weight distribution, density of 0.910-0.925, melting point 122-124 ℃. LLDPE crystallinity is high. The largest application area for LLDPE is film, producing films with higher puncture resistance and tear resistance than LDPE. It has penetrated most LDPE application areas such as food bags, agricultural films, geomembranes, injection molded closures, various containers, paint cans, rotomoulded drums and other hollow products.
